Scientists have reversed the effects of ageing on the skin of mice by blocking the action of a specific protein.

In two-year old mice, Californian researchers found that they could rejuvenate skin to look more youthful.

Further analysis published in the journal Genes and Development showed the skin had the same genetic profile as the skin of newborn mice.

The team said the research would most likely lead to treatments to improve healing in older human patients.

They stressed it was unlikely to be a potential "fountain of youth" but could help older people heal as quickly from injury as they did when they were younger.

The protein in question - NF-kappa-B - is thought to play a role in numerous aspects of ageing.
